Variable "lfdn_QS13" allowing to merge the dataset to the cumulated cross-section of 2013 (ZA5702) was generated wrongly. Thus, not all participants who actually attended to both surveys were able to be merged. This has been fixed.

One participant turned out to be no long-term panelist and have been excluded from the dataset.

"v0a" (sex), "v0b" (month of birth) and "v0c" (year of birth) contained answers of Short-term Campaign Panel 2013 participants which did not match with the answers given in 2013. During the survey this inconsistence answers had been recognized and the participants were asked to correct their entries. By now, the wrong answers have been replaced by the right ones (13 cases in "v0a", 21 cases in "v0b" and 37 cases in "v0c").

German Longitudinal Election Study (GLES)
The German Longitudinal Election Study (GLES) is a DFG-funded project which made its debut just prior to the 2009 federal election. GLES is the largest and most ambitious election study held so far in Germany. Although the initial mandate is to examine and analyse the electorate for three consecutive elections, the aspired goal is to integrate the project within GESIS as an institutionalized election study after the federal election of 2017, and hence to make it a permanent study.
